You got lucky with the purchase since it appears you did not know the differences.

If it has eight spark plug wires and looks like this:



...then it's an LS1. Congrats.

No other type of V8 came in the 98-02 F-bodies (Camaros and Firebirds).

An LT1 came in the 93-97 F-bodies. It looks like this:



This is a L98 (350 TPI, tune-port injection) engine in an '91 Z28:



The third generation F-bodies (82-92) also came with a 5.0 Liter, but all fourth gens came with 5.7.

would have been funny if they sold you a v-6 and they told you that it was an LS1.
